I have the 4 foot stacked Boaphile cages. Great for displaying animals but not as convenient as FB or any other rack & tub system for purposes of routine cleaning/feeding.

I ended up with the ARS 7030 and also the hatchling rack, both with cup holders. Super convenient. Very solid. ARS bailed on making/selling tub liners, which bummed me out for a while. But Superior Shipping stepped in with a better, cheaper liner made of a surprisingly absorbent material, complete with the cup holder cut-out, so all good now.

I see lots of FB racks around -- they look very sound. Lot of Animal Plastics fans on this forum (or used to be).

Luck.
